A cathode active material for lithium secondary batteries, this manufacturing method, and a lithium secondary battery containing this

Title:

A cathode active material for lithium secondary batteries, this manufacturing method, and a lithium secondary battery containing this

Document Type and Number:

Japanese Patent JP6129404

Kind Code:

B2

Abstract:

Disclosed herein is a non-carbon-based anode active material for lithium secondary batteries, including: a core containing silicon (Si); and silicon nanoparticles formed on the surface of the core. The non-carbon-based anode active material is advantageus in that the increase in the volume expansion during charging-discharging can be prevented by the application of silicon nanoparticles, and in that SiOx(x < 1.0) can be easily prepared.
